Title: Circular stone saw - has direct peripheral drive by linear motor, with blade forming secondary part of motor
Inventor: KOESTNER FRANZ DIPL ING
IPC: B23D47/12
Filed: 1973-09-12
Abstract: Circular stone saw has a drive direct and laterally to the periphery of the saw blade. Preferably, the saw blade itself form the secondary part of a linear motor, and the inductor comb is arranged peripherally. Cooling water is applied between the comb and blade, in to the air gap, to form a hydrostatic bearing. The notches needed for voltage build-up are formed between the saw teeth so that the cooling water from nozzles meets the pockets formed like those of a Pelton wheel, to produce a drive by the resulting reaction. The driving element can be set for a constant speed so that the same cutting speed is possible for both small and large saw blades. The shaft can be lighter in construction because of the reduced torsion.

Patent DE-2402587-A1 (DE)
Title: Improved filter cloth for plate and chamber press - having impermeable sleeve around inlet passage to prevent premature blocking
IPC: B01D25/176
Filed: 1974-01-19
Abstract: Plate and chamber press consists of plates with cloths forming chambers to receive filter cake deposited from a slurry feed. The edges of the cloths around the feed passage have an impermeable coating. This can be a sleeve wrapped over and stuck onto the filter surface with a suitable adhesive or by use of self-adhesive material. Prevents premature deposition of cake in the chambers causing the inlet region near the feed channel to block before each chamber is fully loaded thus limiting the filter capacity. This is partic. so where easily filtered materials are involved. Premature blockage prevents blowing out of the feed channel before cake removal. Often the filter must be opened by hand which leads to damage to the filter cloths and to the plates. Also product is saved since hand cleaning means loss of residual slurry in the loading channel.
